This topic describes how to stop the receiver channel on a WebSphere® MQ link while leaving the link itself running.
You may wish to warn the administrator of the WebSphere MQ network that you are about to stop the channel.
Stop mode | |||
Quiesce | Force | ||
Target state | Inactive | The receiver channel moves to the stopping state and the data flow to the WebSphere MQ sender channel stops. When the WebSphere MQ sender channel next tries to communicate with the receiver channel the WebSphere MQ sender channel enters a state of retrying. The receiver channel then becomes inactive. The retrying WebSphere MQ sender channel then reestablishes a session with the receiver channel, and both channels become running. | The receiver channel immediately becomes inactive. When the WebSphere MQ sender channel next tries to communicate with the receiver channel, the WebSphere MQ sender channel enters a state of retrying. The retrying WebSphere MQ sender channel then reestablishes a session with the receiver channel, and both channels become running. |
Stopped | The receiver channel moves to the stopping state and the data flow to the WebSphere MQ sender channel stops. When the WebSphere MQ sender channel next tries to communicate with the receiver channel the WebSphere MQ sender channel enters a state of retrying. The receiver channel then becomes stopped, so preventing the WebSphere MQ sender channel from reestablishing a session. The WebSphere MQ sender channel itself then becomes stopped. | The receiver channel immediately becomes stopped. When the WebSphere MQ sender channel next tries to communicate with the receiver channel, the WebSphere MQ sender channel enters a state of retrying, and then becomes stopped itself. |
If you have stopped the receiver channel, messages sent to the WebSphere MQ link engine will not be received. For more information on stopped states of the WebSphere MQ link and its channels, see States of the WebSphere MQ link and its channels.
If a WebSphere MQ sender channel is started while an MQ link receiver channel is stopped, the request fails with an error indicating that the receiver channel is not available. For more information on stopped states of the WebSphere MQ link and its channels, see States of the WebSphere MQ link and its channels.
